## Description

Sound Master is the live sound engineer&#39;s toolkit, right in your pocket.<br><br>NEW IN 1.1.0 — LIVE MODE<br>Real-time SPL meter, spectrum analyzer and spectrograph on a single screen. dB A/C weighting, Max and Leq, with dB level recording per minute. Freeze captures and overlay up to four curves to compare your measurements.<br><br>🎛 SIGNAL GENERATOR<br>Live-tunable sine, white noise, pink noise and a logarithmic sweep. Plus a system-response measurement (sweep + mic) and an RT60 reverberation-time meter.<br><br>📊 SPECTRUM ANALYZER<br>Real-time FFT from the mic, smooth Mira-style display. 1/1, 1/3, 1/6, 1/12 octave or full spectrum. Current, RMS and Peak curves, dB zoom and a tap probe.<br><br>📐 ACOUSTICS GUIDE<br>Clear reference cards (inverse-distance law, Haas effect, gain staging) and SPL/distance and delay calculators.<br><br>🔊 SPEAKER CONFIGURATION<br>Source coupling (cardioid, end-fire subs), 1D and 3D multi-system alignment, plus official L-Acoustics presets and amp capacities. Delay finder rebuilt for millisecond-accurate alignment.<br><br>Free trial, then €12/year ad-free — or free with ads.<br><br>Note: mic measurements (SPL, RT60, system response) are indicative and uncalibrated. A fast field tool, not a laboratory.
